Gas dripping from air vent on fuel pressure regulator

Recommended Posts

I have a 1994 arctic cat prowler 440 EFI. There is an air vent hose that is connected to the fuel pressure regulator. The fuel pressure regulator is connected to the delivery pipe. There is gas dripping from the air vent hose. I thought this was a gas overflow tube or something, but the parts diagram says it's an air vent hose.

Just wondering if the dripping gas is dangerous. Worried that the gas could come in contact with a hot muffler and explode. 

For all I know it's been dripping like this for a long time. First I noticed it.

Also, why is gas dripping from the air vent hose. Is the regulator going bad? The sled runs fine

Thanks

You may have a rip in one of your carb diagrams or a sticking needle valve and it's leaking out the vent.

Oop's never mind saw it is an EFI. It still maybe a bad gasket letting fuel by.
